Özet:

Lead selenide (PbSe) crystalline thin film produced with chemical bath deposition on substrates (commercial glass). Transmittance, absorption, optical band gap and refractive index investigated UV/VIS. Spectrum. The structural and optical of PbSe thin films were analyzed at different pH. SEM analysis studied for surface analysis and elemental ratio in films. Some properties of films changed with pH and these properties investigated change of pH. The pH values were scanned at 8-11. The optical band gap changed with pH between 1.19 to 1.41 eV. Also, the film thickness changed with pH at 76 nm to 126 nm.
